Need to change layout of WP e-commerce Checkout Page

I want to change a few things on the WP e-commerce checkout page please:
1) Change the font of Address field content so it matches the font of the other fields.
2) Move the Discount and Total Price Field name and content higher up the page so that it appears under the sub-total
3) Change the title of the field ‘Cost Before Shipping’ to Sub-Total.

karennel,
I am having the same issue you had and would like to move the discount and total price field higher so customer can see the adjustment. I would also like to change the title of the field so it makes better sense to customer.
Can you please share how you changed this in wordpress ecommerce?
